The study seeks to compare the efficacy of conventional direct laryngoscopy using a Macintosh blade with the McGrath videolaryngoscope for rapid sequence endotracheal intubation.
The study aims to conduct a multicenter international trial to enroll a maximum of 800 consenting adults who fall under the American Society of Anesthesiologists (ASA) physical status 1-3 category and require elective non-cardiac surgery necessitating endotracheal intubation with rapid sequence induction for general anesthesia. The study seeks to compare the efficacy of conventional direct laryngoscopy using a Macintosh blade with the McGrath videolaryngoscope for rapid sequence endotracheal intubation.

Visualization of the Vocal Cords
The visualization of the vocal cords, defined using the modified Cormack and Lehane classification: Grade I: Full view of the glottis (vocal cords are completely visible). Grade IIa: Partial view of the glottis (only the posterior portion of the glottis is visible). Grade IIb: Only the arytenoids or the posterior extremity of the vocal cords are visible (the anterior commissure is not seen). Grade III: Only the epiglottis is visible (the glottis is not visible). Grade IV: Neither the epiglottis nor the glottis is visible (only the soft palate is seen).
Time frame: From the start time of intubation to time of the end of surgery, up to 12 hours.
Number of Participants With 1, 2, 3, and 4 Intubation Attempts
An intubation attempt was recorded once the endotracheal tube entered the oral cavity
Time frame: From the start time of intubation to time of the end of surgery, up to 12 hours.
Intubation Failure.
Intubation was considered a failure if there was: (1) a failure to intubate after 3 attempts, (2) the need to switch intubators or intubation device, or (3) the need to stop study per anesthesiologist's discretion.
Time frame: From the start time of intubation to time of the end of surgery, up to 12 hours.
